It's just a concept right now but I wanted others to see that the scale doesnt quite match. Right now its just stacked on there and neck is a little too long.

It looks like the easiest solution for now is to try and get original motors and gears for the claw. Anyone here not using original setup? Id buy them.:)

I have some dc motors from robosapien. Think you could use those?

These are what power his legs, then I also have whatever is in his arms and waist.

Thanks Sam but I actually need the gears more. Josh and I are researching DC replacement motors. I found these and ordered them to test out. They can operate up to 12v normal and down to 4.5v.

Hey Bret.talent, can I get 4" of that blue duct?

sa-280 not a bad motor ,but RS-380 has more torque and a very common motor in robotics

@Bret. Thanks! I really appreciate it. Let me know if I can help you out too.

@robotmaker, True. Those are good but the issue was trying to get them to fix in the arm's original motor mount area. RS-380 is longer and larger diameter and wouldnt fit there. Even the RC-280 isnt a perfect fit but I think it may be workable. Idk yet until it comes in. The proof in the pudding will be if the axle sits correctly for the gears to mesh. I figure anything is better than what's in there now.I will let all know after I test it.
